MALT-KILN FLOOR-SECTION.

SPECIFICATION forming part of Letters Patent No. 672,695, dated April 23, 1901.

Application filed March 28, 1900. Serial No. 10,567. (No model.)

To all whom it may concern.- I

Be it known that I, RICHARD BOHNEN, a citizen of the United States, residing at Chicago,

in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Malt-Kiln and Drier Floors, of which the following is a specification.

My invention relates to floors for malt-kilns, driers, and the like, and has for its object to produce a new and improved floor of this description.

My invention is illustrated in the accompanying drawings, wherein- Figure 1 is a plan view of a port-ion of a floor embodying my invention, some of the parts being removed. Fig. 2 is a section on line 22, Fig. 1. Fig. 3 is a section on line 3 3, Fig. 1. Fig. 4 is a view similar to Fig. 3, showing a modified construction.

Likeletters refer to like parts throughout the several figures.

The floors for malt-ki1ns,driers, and the like must be perforated or otherwise formed so as to permit the passage of air therethrough in order that it may act upon the material sup-' ported by the floor. For this and other reasons it is desirable that the frame of the floor be made of comparatively thin material.

In carrying out my invention I provide a framework made up of the thin fiat bars A, running lengthwise, and the thin fiat crossbars B. I have shown the bars B as being wider than the bars A, which is the preferred construction; but it is of course evident that the relative width of these bars may be varied as desired, depending upon the load to be carried by said bars. The bars B are preferably provided with suitable slots or openings B, in which are received theends A of the bars A. Any desired construction may be used; but I prefer to have the ends A, which project into the openings B,s0 mewhat smaller than the bars A, so that a shoulder will be formed which abuts against the bars B. Any desired number of bars A may be used, and the bars B may be placed at any suitable or desired distance apart. A rod or the like 0 passes through the bars B, as shown, and is held in place at the ends and at intermediate points, if desired,by suitable collars O, placed on opposite sides of the bars B. The rod 0 is preferably non-circular, and the openings through the bars B are of such shape as to prevent rotation of the parts when the rod is held in position. It will thus be seen that the rod 0 and the collars O bind and hold the frame parts firmly in position, so that there is no need of rivets or other fastening or holding devices. The floor proper is then laid upon the frame, and as herein illustrated comprises a series of perforated plates D. These plates D are supported upon the frame and are attached thereto by means of suitable fastening devices which pass through some of the perforations in the plates. I have shown these fastening devices E in Figs. 3 and 4 as consisting of hooked or looped parts, said parts being attached to the plates at one end and passing around the edge of one of the bars at the other end, so as to hook over or engage said edge. These fastening devices may be riveted to the plates at the ends where they engage said plates or may be fastened thereto in any other desired manner. These fastening devices may also pass entirely around the lower edge of the bars A or B and have both ends fastened to the plate D, as shown in Fig. 3, or one of the ends may be cut off or formed so that only one end engages the plate D. One form of this construction is shown in Fig. 4, wherein the fastening devices E simply pass around the lower edge of the bars so as to engage them. These fastening devices may be made of one piece or they may be made with a hook or engaging end E, separate, as shown in said latter figure. In this case the engaging end is slipped onto the other part and is held in place by a suitable nut or the like E It will be seen that by means of my invention I am enabled to put the frame and floor together without rivets, and as the fastening devices I use do not make it necessary to mutilate or perforate the bars A and B, I am enabled to make said bars of thin flat strips, which when set on edge give the greatest possible expanse of unobstructed floor-space. The manner of fastening the bars of the frame together makes it possible for me to do away with rivets and the like for this purpose, thus enabling the construction to be made at a much less cost. It will be seen that besides being cheaper this construction is easier to make andis equally as strong as the construc- The floor herein shown may be supported in any desired manner and may be either rigid or stationary or made so that it can be rotated to dump or displace the material thereon. In the drawings I have illustrated a construction in which the floor is adapted to be moved to dump the material. When this construction is used, it will be understood that the floor is made up in a series of sections, like the one shown, for example, in Fig. 1, and each section is preferably supported so that the sections are independent. I have illustrated one means of supporting the floor in this manner, which consists in providinga series of supporting-arms which are formed at one end so as to receive the collars C, said collars being made circular, so thatthey are journaled in these arms. These arms are preferably bent toone side, as shown in Fig. 2, and are supported in any desired manner. As herein shown, the lower ends of the arms pass be- 'to displace the material thereon by simply rotating said rod through the agency of any suitable mechanism.

I claim- A floor-section of driers consisting of a series of very thin flat vertical longitudinal plates, with tenons at their ends, a series of very thin flat vertical cross-plates with holes to receive tenons, a supporting-rod which passes. through the cross-plates, and is provided with suitable fastening. devices to engage the outside surfaces of such cross-plates,

rupted by the lower supports is produced sub- 5 5 stantially as shown and described.
